Nitriding alloys are alloy steels with nitride-forming elements such as aluminum, chromium, molybdenum and titanium. In 2015, nitriding was used to generate a unique duplex microstructure in an iron-manganese alloy ( martensite - austenite , austenite - ferrite ), known to be associated with strongly enhanced mechanical properties.
A schematic of borocarbonitride (BCN) Borocarbonitrides are two-dimensional compounds that contain boron, nitrogen, and carbon atoms in a ratio BxCyNz. [1] [2] Borocarbonitrides are distinct from B,N co-doped graphene in that the former contains separate boron nitride and graphene domains as well as rings with B-C, B-N, C-N, and C-C bonds. [3]
Bromocresol green (BCG) is a dye of the triphenylmethane family (triarylmethane dyes). It belongs to a class of dyes called sulfonephthaleins. [ 4 ] It is used as a pH indicator in applications such as growth mediums for microorganisms and titrations.
β-Carbon nitride (beta-carbon nitride), β-C 3 N 4, is a superhard material predicted to be harder than diamond. [ 2 ] The material was first proposed in 1985 by Amy Liu and Marvin L. Cohen .
Boron nitride tubules were first made in 1989 by Shore and Dolan This work was patented in 1989 and published in 1989 thesis (Dolan) and then 1993 Science. The 1989 work was also the first preparation of amorphous BN by B-trichloroborazine and cesium metal. Boron nitride nanotubes were predicted in 1994 [89] and experimentally discovered in ...
Hexagonal boron nitride is a ceramic powder lubricant. The most interesting lubricant feature is its high temperature resistance of 1200 °C service temperature in an oxidizing atmosphere. Furthermore, boron nitride has a high thermal conductivity. (Cubic boron nitride is very hard and used as an abrasive and cutting tool component.)
Beta carbon nitride - a solid with a formula β-C 3 N 4, which is predicted to be harder than diamond. Graphitic carbon nitride - g-C 3 N 4, with important catalytic and sensor properties. [2] Dicyanodiazomethane (NC) 2 C=N=N, the only C 3 N 4 isomer studied experimentally; Tricyanamide N(CN) 3 - C 3 N 4 monomer (has never been prepared yet)
In Ivan Yefremov's novel Andromeda: A Space-Age Tale (written 1954–1956, published Jan 1957) boron nitride named borazon is routinely used in sublight engine parts and spaceship surface coating. In Randall Garrett's 's short story "Thin Edge" (Analog, Dec 1963) [ 5 ] a fictional borazon-tungsten cable of extraordinary tensile strength is a ...
